The beginning of the song also includes a passage to the tune of Life's Too Short, one of the songs that were deleted from the film after the prophecy storyline and Elsa's role as a villain were dropped. Billboard suggests that the songwriting duo included this Easter egg because they 'know exactly what the fanbase wanted'. In 'Making Today a Perfect Day' there is a lyrical reference to 'Let It Go'-Elsa notes to Anna that 'a cold never bothered me anyway', this time re-purposing the line by referring to an actual cold. At the premiere of Cinderella and Frozen Fever at the El Capitan Theatre in Hollywood, California, on March 1, 2015, Josh Gad told USA Today, 'I want to apologize to parents everywhere for the fact that children are going to be singing a whole new Frozen song.'

In late December, the co-directors told the Associated Press 'There is something magic about these characters and this cast and this music.

In a mid-October interview, Idina Menzel revealed that the cast had already recorded their vocal tracks, stating 'We just worked on a short for Frozen.' On December 3, 2014, it was announced that Aimee Scribner would be a co-producer and that Frozen Fever would debut in theaters alongside Walt Disney Pictures' Cinderella on March 13, 2015. On the same day, Variety announced that the short would be released in early 2015 under the title Frozen Fever, with Chris Buck and Jennifer Lee returning as co-directors, Peter Del Vecho returning as producer and a new song by Kristen Anderson-Lopez and Robert Lopez.
